In Greek mythology, Asteria (/əˈstɪəriə/; Ancient Greek: Ἀστερία, "of the stars, starry one") was a name attributed to the following eleven individuals: the daughter of Coeus, an Amazon woman, Heliad, Danaid, Alkyonides, the Consort of Phocus, the consort of Bellerophon, the daughter of Coronus, the daughter of Teucer, an Athenian maiden, and a character in the opera "Telemaco". Each of these is detailed below.

The Titan goddess of nocturnal oracles and falling stars, Asteria flung herself into the Aegean Sea in the form of a quail in order to escape the advances of Zeus, and became the "quail island" of Ortygia.[3] This then became identified with the island of Delos, which was the only piece on earth to give refuge to the fugitive Leto when, pregnant with Zeus's children, she was pursued by vengeful Hera.[4]
